More Information
Summary:The present invention is a film having at least one reflection band in which the reflectance is 30% or greater continuously in at least a 100-nm range in a wavelength range of 1200-1800 nm when light is incident from at least one side, the mean transmittance in a wavelength range of 430-600 nm is 70% or greater, and the average value of the axial rigidity of the film in the principal orientation axis direction of the film and in the direction orthogonal thereto is 45 N/m or less.
